I don't want to use a red grease as it could stain in the event of a mishap while taking the seats in/out. Leaning toward just plain old Vaseline.

What works well and isn't messy?

I used a white lithium grease after thoroughly cleaning my rails. Once they're clean they slide like new with very little grease. Remember grease attracts dirt and dust.

I used teflon bicycle chain lube and it seems to be working well. I'm not sure they slide quite as effortlessly as with grease but should trap dirt and gunk. The seats are easy to adjust.

Grease may attract dirt; I use Teflon spray, lightly !
My seat had always been hard to slide; li put 1/4 nylon spacers between the track bolts and the seats; sliding became easier.

@socalandy suggested using a dab of wheel bearing grease and not white lithium for the reasons stated above.

Thanks all. I think I will try the teflon. It also just occurred to me that having removed the tracks from the seats to recover them, they are most likely out of alignment. So I think that is my first order of business.

Finish line makes a pure Teflon grease. Expensive but works great. I bought a tube, actually a syringe of it on amazon.

Silicone spray is awesome, but it doesn't stay. Hence... grease. Just a good white grease applied less than you think it would need. It's not a new rocket science problem.

Do not use Vaseline. I made that mistake before.

The first time you get a hot day, it’s melts into oil and makes a mess.

White lithium grease seems logical to me.

I like to work with “Sil Glyde”. I have been using this grease for a while now. Never had an issue. Alway has good rating and my seal of approval.
